of operation into transportable position, and

after transportation, de ositing it.

|The general object o the invention is to provide simple and efficientpower mechanism for raising and positioning the load and effectivelycarrying 1t during transportation and readily depositing it underthe'accuraie control, of the operator.

lMore particularly my invention provides a truck equipped with .aflexible member' extending over a suitable boom hinged at its lower endto the truck fra-me, the load being received in a suitable supportpivoted to the lower end of the boom. The flexible member first raisesthe load by ti ping the boom over the truck body and tien 11p-ends theload by rotation of the pivotal support into a convenient transportableposition. A suitable spring mechanism supports the tipped boom andautomatically returns it to loaddischarging position, when the relaxingof, the iexible member permits such movement.A

. My invention may be embodied in a truck elevating and upending paperrolls, and transporting them and thereafter depositing them.

The above features and others contributing to the eliiciency of themachine are hereinafter more full explained in connection with anapprovedy embodiment as shown in the accompanyin drawings. The essentialcharacteristics o? my invention are summarized in the claims.

` Fig. 11 is an enlarged vertical section of the same taken on the line11-11 of Fig. 10. Fig-12 is a transverse section of the same on the line:l2-12 of Fig. 11.

As shown in Figs. 1 to 4.-, 10 indicates the frame body of the truckwhich is supported vby rear wheels 11. and forward wheels 12. Theseforward wheels are on Opposite sides ht and transverse members securedto t e rame member l0. rlhis housing may carry a suitable motor (notshown) for rotating the front wheels, and these shown. On the upper partof the front housing is a s ace 15 suitable for a storage battery fordriving the truck, and this saine battery may be availed of foroperating the cable-winding' mechanism hereinafter described.

The construction of the frame, wheels, housing, etc., above mentioned,does not enter into the present invention. 'They may if desired beformed according to Patent N o. 1,260,145, rented March 19, 1918, to theElWell-Par er Electric Company as assignee of Clyde E. Cochran. I

In the present invention, I hinge to the rear end of the truck frame 10a boom 20.

This is composed of an approximately up' the boom of a front housing 13com.

boom in original posisteered by any mechanism, not

shapedkforxn and suitably braced as at'23. Between the armsof thechannelbeam and rigidly secured to them` at" their lower ends is acasting 2L which is pivoted at 22 on a horizontal ivot to thetruck'frame.

The casting 21 is provided with 'bearings adapted lto receive in pivotalrelation the rectangular, having an elongated hub `16 ex-I 'tendingforwardly around a central opening. The lower corners are provided withears 1'7 adapted to be received on a shaft 22 secured to the' rear endof the truck 'body 10. The sides may be suitably flanged to re- .J ceivethe ends of the bent channel beam cnstituting the boom 20, which may besecured thereto in any desiredi manner.

arcuate scoop l50 end 56 and projecting lugs 57 mounted on The loadsupporting member preferably consists of the casting illustrated inFigs. 6 and 9, to which is suitably secured as by bolts or rivetspassing through holes-27, the having a partially closed suitable plates55 whichare secured to the scoop 50. Locatedbetween the plates 55 arereinforcing ribs' 58 between which an arcuate retaining latch 49 isslidably mounted. Projecting forwardly from the center vofthe casting 45isla tapered hollow stub vshaft or axle 31,

having inserted at the for- ,ward end a hardened steel pivot 32 having areduced threaded end adapted to receivea nut 3 3. v The stub shaft 31-isadapted to rotate in` ball races 34 within the rear portion of -thecasting 21, while the forwardly extend- 'ing pivot 32 has a bearingwithin ball races 35.A A protecting cap 36 may be secured as by bolts 37to the outer end of the hub 16.

Depending from the top portion 24 of the boom at the junction of thearms of the in-l the vdrawing in o verted U`shaped member is a pulleyblock 25 over which extendsa cable 30. One end of this cable vpasses toa suitable windingl drum as illustrated at 1137in Figs. 1 to '4.

The other end-of the cable may be suitably attached to either of thelugs `57 ,on the scoop'50.

. By properly locating the lugs 57 v,with re- Ilation to the centre ofgravity ofthe load due tov the moments actin on 'the scoop 50 .the cable30 'when.at tached to the lug 57, can be so determined that the rotationof the winding drum at 11S-will first tip the boom forwardly over therear Aportion of the truck, as'shown 1n Fig. 2, with the load remaininginthe hori-4 zontal position and upon a further drawmg .in of thecable30 the scoop and load will be lof the members 60 `and rotated inthe bearings 34 and 35 untilthe load will be up-ended into asubstantially upright position as shown in ig. 3, the ear 152 and lug151 acting as a position stop.

The pivotally supported casting is provided with a shoulder 59 whichisin theposition as illustrated vin Fig. 9, when the scoop is horizontalas in Figs. 1 and 2. The

shoulder 59 is adapted to engage and opf erate automaticl mechanism forcontrolling the cable which will be herinafter more fully described.

, Toward the ou er end ofthe-scoop a load l'retaining latch 49 isslidably mounted between the arcuate ribs 58 and engages a substantialportion of the circumference of the roll when 4drawn out to the rolllocking position.

On each side of the boom I provide a suitable resilient connection witha portion of the truck frame in front of the pivot 22. As illustrated, Ipreferably pivot to each arm of the channel beam constituting the boom,

theA upper ends of the tubular sockets 60. vExtending from these socketmembers, co-

`axially therewith, are rods 62. These rods extend loosely' throughtubular heads on partially tubular members 64, pivoted at 65 to theframe 10. On the lower ends of the .rods 62 are nuts 66 limiting theupward f movement of the rods. Surroundingv the reduced upper ends ofthe rodsand bearing against ,collars formed at the junction of thereduced and full sized portions of the rods and extending into the .boreofthe members 60 and seated against the farend of"such bore, arecompression springs 67.

The construction described provides two lateral tie members for'the boomadapted to limit its outward swing to substantially vertical position,as shown in Figs. 1 and-4. These springs provide an -elastic cushion forthe boom when it is dra'wn forwardly by the cable over the truck frame,the rods 62 telescopng within the tubular' members 60 and 64, allowingthe socket'member 60 to approach the -tubular member 64 as illustratedin Figs. 2 and 3. The engagement l 64. forms a positive stop limiting.the inward swing-of the boom. When the cable isl released the reactionof the springs and the weight of the load raises the boom to the'upright'position of Fig. 4, suitable for dischargin .the load.

j Fig. 1 indicates at a paper roll lying horizontally in the scoop 50.lThe lugs 57 are located on the scoop 50 as hereinbefore stated in such'amanner' that a tilting `movement of the `load will take place before theload rotates on the pivot 45. I have found that such anarrangementrequires one or more terminalsor lugs for the cable`3-0 andthe end lof the 'cable is attached to the upper' or lower lugl 57 inaccordance with the length of the paperroll being handlede Cildescribed, the truck maybe backed into position adjacent to a horizontalpaper roll and the latter rolled into the scoop. The endof the cable maythen be attached to the scoop and the winding motor started.

. The boom will immediately be tipped over the truck frame and yieldablysupported,

thereby raising the'load, and thereafter tilting thesame intosubstantially upright position resting onl the end 56 of the scoop,ready for transportation. When the desired new location is reached-*thevpaper roll is deposited simply by paying out the cable 30.l The. firstresult of this paying-out movcnie'it'is for the springs 67to raise thebooin suiiciently for the weight of the loadV to complete the movementinto upright po'- sition as shown in'Fi'g. 4, whereupon theedge of thepaper roll, away from the end ofthe truck, will drop by gravity to thefloor and the truck may be moved -forwardly withdrawing the end 56 ofthe scoop 50 from the roll and leaving it'depositedA in uprightposition.

Any suitablewinding mechanism may bel provided for pulling in and payingout the cable 30. I find it very convenient to use an electricwinchgfpnthis purpose, which provides a winding drum, a motor' gearedtoit and suitable mechanism making the device self-locking ,whenever themotor rctation stops, but enabling the winding in l at will and also thepayingou't of the cable whenever desired, by rotating the drum `in theunwinding direction faster than gravity and the action of the springs 67tend to rotate it.

A vconvenient form 0f winding mechanism as above outlined is illustratedin Figs. "10, 1l and 12, where the wvinding drum 100 is 0n a shaft 101which lcarries a spur gear 102 meshing with a piniony 103 on a shaft,

104. A spur gear 105 on this4 shaft meshes with a pinion .106, on asleeveT 107 which,-

is looseon the shaft 101i. 'Surroi'lhdipg the sleeve 107 is a 'spur gear108 WhlCh 1S 0,01% nected with thfe'sleeve by means allowing independentmovement- .fD-l" 01113 a fraction of a rotation. This'ge'ar 1,08 meSheS11th a pinion 109 (Figs. 1 to 4') on an eXtenslon of the armature shaftof a motor 110. .Between'the gear 108 and the piIlOH 106 1S, a frictionbrake effective whenever the raising rotation stops. This consists,assliown,

of a disc 111 rigid with the sleeves 1.07, an annular friction member112 alonerslde 0f the disc andA held stationary by engagement with thecasting 113` of the winding mechanism, and an annular cam,member 114 onthe other side of the yfriction member 112' and loosely splined onthe'sleeve and having on itsouter side a face cam 115. This cam isadapted to be abutted by a complementary cam'll'w-hich is rigid on thesleeve 'ing direction the mechanism provides first for relievingthebrake, and then for furnishing a direct train of spur gearing betweentlie armatureyand the raising drum. VVhenthe raising rotation ceases thetendency of the load is to rotate the train of lgears in the oppositedirection, and as the ,107 and has a portion extending within the gear-108 moves in this backward direction the brake member 114 lags behindit so that the4 brakefbecomes applied by 'reason of the inclined actionof the cams andthe load is. held. v

To lower'the load the armature is simply driven in the reverse"fdirection"fromwthe raising movement. This turns the gear 108Ybackwardly faster than the load -would turn it, andfin this movementwebs .1,19 on this gear engagelugs 120 on v'the cam-.member 114, andcarry-it around so that the, brake is not applied.

, The engagement of the webs 119 with the lugs 120 takes place beforethe other ends of the notches 117 engage the lugs 118. vlvhenever thislowering rotation of the armature SOPS., the tendency of the load topull the train of gearing applies thebrake, as' already described.

v It will be realized from the above descrip- 'tion that the deviceillustrated is self-locking whenever the motor rotation' ceases, whetherit has been raising [or lowering the load. It is to be `understood,however, that the winding mechanism. so illustrated and described issimply set out by wayzfofzillustration, as any self-locking windingmechanisi may be used. The particular winding mechanism shown isbelieved to be manufactured under Patent No. 1,020,014,

11i-g from the gear housing 113. All of these 2 and 3, and at the sametime the cable may simple mechanism which 1s shown 1n Figs. 1 to 4 andwhich `bracket when t YRigi'dly connected with the pass directly fromthe winch to the top ofv the boom and obtain a suiiciently direct pullfor readily tipping the latter.

As one of the uses of the present truck is for handling paper rolls, itis desirable to provide automatic mechanism to stop theA inward swing ofthe boom at a definite point, ythereupon tilt 'the roll into asubstantially uprightposition and then stop the operation of the'windingdrum, It is desirable also to have the mechanism under the constantQontrol ofthe operator for lowering the roll so that it may be gentlydeposited in an upright position from the truck. I provide a foreffecting these results,

will now be described.

130 indicates a suitable double-pole double-throw knife switch adaptedto break the current in either direction on the raising motor 110, thebottom position of the switchbeing for raising and the 'top position forlowering. This switch is operated by a push and pull rod 135, whichcarries an operating handle 145, and is connected with the arm 134 of abell crank, pivoted at 133 on a bracket .secured to the framev 13. Theother arm 132 of the bell crank is connected by a link 131 with theswitch. The rod 135 slides loosely through a suitably su ported bracket136 and has two collars 13g equally spaced on the rod from the e switchand associated parts are in open or neutral position. Surrounding therod, between the collar 137 and the two brackets 136, are compressionsprings 138 so that the handle can be moved in either direction onlyagainst the springs, which tend to restore the handle to neutralposition. The knife switch is swung into raising position by an outwardpull on the handle 145 which causes a downward pull on the link 131through the bell crank described. bell crank is a third arm 139 havingsecured thereto a collar 140 slidably receiving a rod 141 havingadjustably fixed collars 142 and 143 thereon.v A

To start the raising operation the operatori, simply pulls out thehandle 145. The motor now operates and winds f'up the cable 30, tippingthe boom forwardly over the rear portion of the truck and at the vsametime raising the paper roll. As the boom is coming into its finalhorizontal position as shown in Fig. 2 as the drum 113 continues to:kdraw the cable in the scoop containing the paper roll is then'revolvedabout the pivot bearings 34 and 35 until it is tilted intoupendedposition. As the boom approaches its extreme forward tippedposition the rod 141 slides idly through the collar 140 until the fixedcollar 143 thereon approximately reaches the collar 140. i

Asthe paper roll approaches its up-standing position the shoulder 59strikes the upstanding arm on the bell crank 68 projecting thru anopening 27 in the casting 21, and moves the arm 68 downwardly from thepositionl shown in Fig. 3. This movement is transmitted through the rod141, the collar 143 engaging and moving the collar 140 secured to thebell crank 132, thereby pushing the link 131 upwardly and moving thevswitch into neutral position. This opens the current to the motor andthe self-locking mechanism retains the load in such position.

To lower the load the operator pushes in on the handle 145, whichmovement pushes the link 131 further upward and swings the .knife switch130 into its upper engagement to direct current in the reversingdirection to the motor, which allows the cable to pay out, the loadbeing loweredl as long as the handle is heldin. Whenever the operatorrelieves the force on the handley the springs 138 restore the handle toneutral position, which swings the switch open and stops the motor,

and the selflocking mechanismI holds the load.

When the load has been lowered to the; positionshown in Fig. 4, thepaperroll will tip under the iniuence of gravity until the edge remotefrom the truck strikes the floor. truck may then be moved forwardly,which will withdraw the scoop from the roll and leaveiyt deposited in11p-ended position. As shown in Fig. 1 the lower side of the scoop, whenin horizontal position, is heavier than the upper so that afterdepositing the load, after the Fig. 4 position gravity will cause theempty scoop to return to horizontal position. As it comes into suchposition the lug 150 (Fig. 9) the under side o f the bell crank arm 68and raise the same from the Fig. 4 position to that shown in Fig.,1,thereby restoring the switch 130 to neutral position.

By the above described means the load- Isupporting member may be raisedandtilted and then lowered under constant control of the' operator, andyet be automatically. stopped upon reaching extreme movement in eitherdirection, thereby preventing any possible damage fromv failure of theoperator to will strike The has been reached, l

Theear 56 on the lowerend of the 'scoop is beveled along the outer edge toprevent damaging of the roll when the truck in a vertical position, andthe counterweight 153 acts to tilt the scoop to a horizontal position.

Furthermore, the roll may be transported while in this position and thenbe deposited at the new loca-tion in a vertical position or may berotated fromv a vertical to a horiand then bel deposited.
